BRAKE BAND.

Application filed December 11, 1922. Serial No. 606,084.

To all whom it may concern.'

Be it known that I, JOHN O. SOMERVILLE, a citizen of the United States,resident of Minneapolis, county of Henne-pin, and State of Minnesota,have invented. certain new and useful Improvements in Brake Bands, ofwhich the following is a specification.

It is frequently necessary to remove `a brake band of a power propelledvehicle for the purpose of renewing the lining or repairing some of theparts, and in some types of cars such removal necessitates considerabletime and labor in detaching and removing various mechanisms to allow theremoval of the band and its re-insertion to its working position.

The invention consists generally in various constructions andcombinations all as hereinafter described and particularly pointed outin the claims.

In the accompanying drawings forming part of this specification,

Figure 1, is a view partially in section of a brake band embodying myinvention;

Figure 2, is a detail view of one end of the band showing the connectinglug removed;

Figure 3, is a plan view of the removable ludetached from the band;

igure 4, is a perspective view of the locking plate mounted on the lug;

Figure 5, is a sectional view on the line 5-5 of Figure 1.

In the drawing, 2 represents a metallicy brake band of ordinaryconstruction having a suitable lining 3 secured thereto by rivets 4. Alug 5 is seated on one end of the band and has a foot plate 6 that isrigidly secured to the band by'suitable means such as rivets 7. Theopposite end of the band has a similar lug 5a correspondingsubstantially to the lug 5 and having a foot-piece 6a, but instead ofbeing rigidly secured to the end of the band, the foot-piece 6a hascomparatively large circular orifices therein at suitable intervalswhich are adapted to receive heads 8 formed on rivets 9 which aremounted in the end of the brake band; the heads being seated firmly onthe outer surface of the band. The heads 8 are provided with annularrecesses l0 which when the parts are assembled, are outside the surfaceof the foot-piece 6a. Y

A locking plate 11 has holes 12 therein to receive the heads 8, saidholes having slotted extensions 13, theedges of which enter the annulargrooves l() and allow endwise movement of the locking plate 11, suchmovement being suiiicient to lock the foot-' piece 6a firmly on the endof the band. The locking plate is also provided with guide slots '14 toreceive pins l5 mounted on the foot-piece to prevent accidentalseparation of the locking plate and lug. The end of the locking plateadjacent the lug has an outwardly turned portion 16 having a slot 1"(`therein adapted to register with the corresponding slot 1S provided inboth of the lugs 5 and 5a; said slots being U-shap'ed in form andadapted to receive the connecting bolt 19 by means of which the lugs andthe ends ofthe brake-band are joined and drawn together, said bolthaving the usual washers 20 and compressed spring 21.

It will be evident from an examination of this device that when the bolt19 is loosened suiiiciently to allow endwise movement of 'the lockingplate 11 that it can be moved to its release position and the foot-piece6a and the lu 5a thereon readily detached from the end cig the band andthe band thereupon removed from the housing by endwise movement. Whenthe partsk are reassembled again, the foot-piece of the lug 5a, isplaced in position, the locking plate slipped up against the lug 5, andwhen the bolt is tightened, the parts will again be rigidly connected.

I claim as my invention:

1. In combination withabrake band, .a lug adapted to receive aconnecting bolt and Ahaving a foot-piece seated on said band, rivetsmounted in said band and having heads projecting outwardly therefrom, alocking plate having an end to fit said lug and be engaged by said boltand provided with means for interlocking with said rivetsfo-r securingsaid foot-piece on said band.

2. In combination with a brake band, a lug having a foot-piece seat-edthereon and provided with a series of comparatively large orices, rivetsmounted in said band and having heads projecting through the orifice andsaid foot-piece and extending outwardly beyond the same, said headshaving annular grooves therein, a locking plate having keyhole slots toreceive said heads and slide longitudinally thereon, said plate havingan end to iit the surface of said lug and be clamped thereon when theends of said band are. drawn together.

3. In combination with a brake band, a

lug having aslot therein secured to one end of said: band,. ak secondklug detachably mounted on the other end of said brake. bandV and alsohaving a slot ther.ein a bolt, lit? ting said slots for drawing saidlugs and the ends of said band together, a looking plate mounted on saiddetachable lug` and having means for temporarily loeking, said.

lug on said band, said plate having a slotted endto registerwith theslot in the adjacent lug" andi be' engaged byA said. bolt for,- hold-Vingl said locking plate in itsv locking position.

4.2 A transmission: band, comprising a band ofy resilient materialprovidedfi with;

studs. projecting from. one face, an ear 'formed withl openingsv toreeeivethe studs oft the band andi removable from the studs7 and afasteningmember to-span the space between. thev studs andi having aseparable interlocking engagement with the studs to sec-ure the ear vto*the band;

5. A' transmission band, Comprising a bandl of resilient materialprovided with ings being of'such relative dimensionstha-t' the ear; andbandfare substantially n0n-slid able one relatively to the other,- andmeans interlocking with the studs to secure the. ear in position.

In Witness whereof', I have hereunto setv my hand this Gth day of'December,l 1922.
